Chu Yuesheng didn't know that in the past few seconds, the entire Central City, including his home, had already gone around in front of the Ghost Gate, and was almost blown up into a spectacular sinkhole landscape.

Now he was still thinking about what Gong Zimeng had just said, and he was a little happy that his doubts had been solved.

No wonder the way the robot moves doesn't match its theoretical power furnace output, it turns out that there is an additional power source. In this case, as long as you find that power source, destroy it, and use the power furnace of this robot itself, it will become a high paraplegic that can't even move in an instant, and become a piece of meat on a cutting board, which can be concocted at will.

But the question is, where is the power source?

In order to figure out the location of the power source, Chu Yuesheng first needs to figure out how the robot obtains energy. Only by determining the type of power source obtained, can the corresponding power source be determined according to the type.

With the current technology tree of human beings, although they have mastered a variety of energy sources such as wind energy, water energy, fossil energy, and even fission energy and fusion energy, the dominance of electric energy is still eternal. Inertial thinking allows human beings to habitually convert all energy into electrical energy that is convenient for storage, control and utilization, and then use current to control the start and stop of various electrical appliances to provide power for electrical appliances. Chu Yuesheng didn't think that this weird robot could jump out of the strange circle of human inherent thinking, or that he could only think so. Because this strange circle also encircled Chu Yuesheng himself, in addition to electrical energy, if this robot was really directly driven by other energy sources, then Chu Yuesheng really had no way to guess what kind of energy energy it was using.

This is the precipitation of the imagination of the entire human race for hundreds of thousands of years, and there is no way to break it by relying on Chu Yuesheng alone.

So, if the energy used by this robot is limited to electricity, and the source of electricity Miyako Dream is very sure that the ground......

There is dirt under your feet, and as long as any current is directed into the earth, the electric potential should be zero. Chu Yuesheng and Gong Zimeng's feet stepped on the ground and did not receive an electric shock, which means that there is no problem on the ground.

Normal current cannot be conducted through the ground, but Chu Yuesheng quickly thought of a situation where even walking on the ground would be electrocuted, and that was the step voltage.

When a wire with high voltage electricity falls to the ground, the potential of the landing point is the same as that of the live wire, and the current will flow from the landing point of the wire to the earth, so the ground is centered on the wire landing point, forming an electric potential distribution area, the farther away from the landing point, the more dispersed the current, and the lower the ground potential. In the range of step voltage, the electric potential at different positions is different, and the difference in electric potential will cause a potential difference between the two points - the electric potential difference, which is the basis for generating current.

And although the robot was very large, the width of the step between the two feet was not very large, and it was three or four meters above the sky. If such a short distance can generate a strong current that is enough to drive the activities of a robot of that size, then with the stride of Chu Yuesheng and Gong Zimeng, it should be enough to feel the current. But the fact is that Chu Yuesheng and Gong Zimeng came all the way, not to mention the current, and they didn't even feel static electricity. This kind of haunted factory building does not feel like a match with the diffusion potential field of the concentric circles of step voltage.

I couldn't find where the electric potential field of the step voltage was, could it be that my own speculation was wrong? Under the heavy blow of reality, Chu Yuesheng's originally firm confidence couldn't help but waver.

Chu Yuesheng himself is not a detective, and the only thing he is stronger than Gong Zimeng is probably that his understanding of various technologies of human civilization is deeper than that of Gong Zimeng. But he is not a professional in these aspects, and the channel for understanding that knowledge is actually a textbook. And textbooks like that...... Quality education, everyone will reach the pinnacle of their academic life in high school, know astronomy and geography, know the composition and structure of cells and calculate the trajectory of satellites, but that is completely in preparation for the choices that need to be made after the college entrance examination in the future, and requires a comprehensive but general understanding of almost the entire knowledge network. Because he didn't know enough deeply, if he really wanted Chu Yuesheng to analyze whether there was high-voltage electricity here, he was actually blindsided.

Chu Yuesheng really wanted to help, in the process of Gong Zimeng's confrontation with that huge robot, he could only act as a spectator and a burden without actual combat ability, which made Chu Yuesheng, who was an adult and a man at the same time, feel very unwilling. Even if he can't directly participate in the battle, even if he can do some auxiliary work on the side, Chu Yuesheng can accept it calmly.

Only like now, doing nothing, not being able to do anything, this made Chu Yuesheng feel a great sense of frustration in his heart, and once again felt lost that his ability could not be directly used in battle.

Gong Zimeng didn't know that in this moment of lightning, Chu Yuesheng's brain could turn so many twists and turns. Because she can't blow up the whole environment directly, she is also struggling to think of another way to solve the problem. But the education she received has always been that since it can't solve the current problem, then solve the root cause of the problem, as long as the chessboard is smashed, no matter how difficult the Zhenlong chess game will be solved, although simple and rough, but it is undeniable that for the strong, this is indeed an effective and most efficient method. As a result, she was suddenly given a limited range, only allowing her to act within a box, which is like letting a fifth-generation fighter lower its altitude to circle and fight with a third-generation fighter, it is not impossible to win, but the discomfort and disgusting in this process may not be described in one or two sentences.

Neither of them had much on the giant robot that escaped, but the other party obviously did not give up the idea of killing Gong Zimeng and Chu Yuesheng together. The reason for escaping is only that I realized that I couldn't take advantage of it at close range. Now, the robot has run to the place that is most beneficial to itself, and without the knowledge of Gong Zimeng and Chu Yuesheng, it is ready to attack the two of them again.

A metal spear wrapped with electric light slowly aimed at the direction where Gong Zimeng and Chu Yuesheng were at this moment.
